Equidistant stop function: Takes the maximum frequency deceleration time as datum line, the inverter stop rotation
running turns as same as the maximum frequency stop rotation turns after inverter performed stop command with
any frequency. For example, the maximum frequency is 60Hz, deceleration time is 1s. If the maximum frequency
decelerate stop rotation turns is 5, so the stop rotation turns also is 5 with 40Hz frequency given. The deceleration
time of equidistant stop during difference frequency given change as following curve diagram show.
Note: 1. This function is disabled when the frequency given less than10% of maximum frequency, the
inverter decelerate based on the deceleration time, it will not performed the equidistant function when the
frequency given less than 10% of maximum frequency.
2. The overvoltage and over current suppression occurs when the deceleration time is too short, the actual
of deceleration time will be longer, and the equidistant function can’t be performed.
